His discovery of Jupiter's major moons (Io, Europa, Ganymede and Callisto) revolutionized astronomy and helped speed the. Galileo also looked toward some of the other nebulous stars that Ptolemy had listed, including the Praesepe, or Beehive Cluster in the constellation of Cancer. His university salary could not cover all his expenses, and he therefore took in well-to-do boarding students whom he tutored privately in such subjects as fortification. Given its position in the sky, with the planet still months away from the opposition, Galileo must have stayed up until around midnight to observe it. Before the invention of the telescope, Venus and the other planets just looked like bright stars.

Brahe catalogued over 1000 stars. By now, Galileo was convinced the tiny stars all orbited Jupiter. The statement: "Planets sweep out equal area in equal time." Indeed, he transformed the way in which people perceived the world and had a life and career that some may not be so familiar with. Examine Aristotle's model of the solar system and note its failure to explain phenomena like retrograde motion. He was the first to see, through the lens of the telescope, the wonders of our galaxy sights that moved him to profound gratitude to God. Galileo sparked the birth of modern astronomy with his observations of the Moon, phases of Venus, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way Galaxy.

Moreover, the map Harriot created of the Moon in 1612 or 1613 is more detailed than Galileo's. can detect fainter stars. Galileo then began to prepare himself to teach Aristotelian philosophy and mathematics, and several of his lectures have survived. The Polish astronomer Nicolaus Copernicus had proposed a Sun-centered universe some 70 years earlier, but his model had failed to completely take hold. All the models were more or less equivalent. During this period he designed a new form of hydrostatic balance for weighing small quantities and wrote a short treatise, La bilancetta (The Little Balance), that circulated in manuscript form. When viewed from the Earth, the celestial sphere (the background of stars) moves east to west on a daily basis.

After hearing about the "Danish perspective glass" in 1609, Galileo constructed his own telescope. A has a smaller mass than B. From his sketches, he made estimates of their heights and depths. Credit: NASA/JPL/DLR | More about this image. In his times, Marius was publicly condemned as a plagiarist. One of the things that Galileo could not observe with his rudimentary telescope was the rotation of the stars, it is the fact that the stars rotate around their axis. b) Briefly explain how ONE specific historical event or development during the period 1890 to 1945 that is not explicitly mentioned in the excerpts co Galileo did not discover Saturn.

And over the course of a decade Galileo continued to make more telescopes and his most powerful one magnified images about ten times. He was born in Pisa on February 15, 1564. By the beginning of January 1610, the planet Jupiter, just one month past opposition, was now moving through the eastern, Until that time, many believed in the Earth-centered universe, where everything orbited the Earth. He was able to make out mountains and craters on the moon, as well as a ribbon of diffuse light arching across the sky the Milky Way. Galileo was one of the first people to use a telescope to observe the heavens. As a result, Galileo was confirmed in his belief, which he had probably held for decades but which had not been central to his studies, that the Sun is the centre of the universe and that Earth is a planet, as Copernicus had argued. Galileo's discovery proved that the Copernican model of the solar system, in which planets orbit the Sun, was correct.

Critics of Copernicus' sun-centered cosmos asked, how could the Earth drag the moon across the heavens? He also proved that comets were not just components of Earth's atmosphere, but actual objects traveling through space. He drew and described them as handles on the side of the planet and so the mystery remained.
